Neodymium iron boron, also known as NdFeB magnet (NdFeB magnet) is a tetracrystal formed by neodymium, iron, boron (Nd2Fe14B).
Neodymium magnets were discovered in 1982 by Masato Sagawa of Sumitomo Special Metals in Japan.
The BHmax of this magnet was greater than the BHmax of a samarium cobalt magnet, the largest mass in the world at that time.
Later, Sumitomo Special metals developed successfully powder metallurgy process.
General Motors developed the melt-spinning process, which produced NdFeb magnets.
This magnet is the most powerful permanent magnet and the most commonly used rare earth magnet
